[✓][SUG][ED] Min/Max Zoom Factor Indicator

[WillLem]

Having a Zoom in slider to tell folks that yes you can zoom in.

This is a good idea. Maybe we can workshop some ways this could be represented visually.

OK, I've gone ahead and added a zoom factor indicator to the corner text (where the X/Y co-ordinates are displayed):



It's relatively unintrusive so there's probably no need to make this optional. It shows the current zoom level (and users will get to know what is the min/max possible allowed by their monitor/screen res), so this should serve as an indicator of whether zoom in or out is possible from the current factor.

I'll keep the topic open in case anyone has any ideas/suggestions, but this should otherwise be considered resolved.

Implemented in commit 8d1441b.
